I like the comparisions of Kaj. Translated to a nontechnical analogy, they use to be like that:
Somebody says to kaj's two years old child: kaj, look at vandam, he has so many muscles, and he is so fast compared to your two years old child.
And kaj answeres:
"Yes, but does vandam fit in a toy-car like my son? If you weight vandame, how many kg's does he have? 70? 80? My child has only 10kg!! "
